ABSTRACT:
The horizontally extending rotary operator shaft of an electric lamp socket switch is joined releasably to one end of a connector the opposite end of which is connected through a coupler to one end of an elongated extension which hangs freely downward for rotation about a vertical axis. The coupler may be a length of snake chain, a length of link chain, wire, rotor or other flexible or resilient material confined for rotation in a rigid sleeve having its ends disposed at right angles to each other, or bevel gears disposed perpendicular to each other, or a link pivotally interconnecting the connector and extension and confined in a sleeve which maintains the included angles between the link and the connector and extension to obtuse angles of sufficient magnitude that, as with the other couplers, rotation of the extension about a vertical axis results in rotation of the connector and hence the rotary operator shaft of the switch about a horizontal axis.
